Question 139882: please help me solve.
Driven from Albuquerque,NM to Rock Springs,WY. The average speed is 55 miles per hour. The Route is along interstate 25 to Cheyenne, Wy, then to interstate 80 to Rock Spring.
I added it up to 799 miles.
What would be the total driving time to the nearest half hour?
I figure it to be 14.5 hours.
Please show me the steps. I do not know how to write it out. Is this correct?

You can put this solution on YOUR website!
Assuming that you have correctly calculated the total mileage from Albuquerque, NM to Rock Spring, IL(?), to be 799 miles, driven at a speed of 55 mph.
The total driving time is:
T+=+d%2Fr Where: T = total driving time, d = total distance, and r = rate (speed). Making the appropriate substitutions, we get:
T+=+799%2F55
T+=+14.5 hours, to the nearest half hour.
Your answer is correct!
